[PATCH] PPC64: Don't try to claim memory from OF at 1GB mark
Some RS64-based machines (p620, F80, others) have problems with firmware
returning 0xdeadbeef instead of failure to allocations that end at the
1GB mark.
We have two options:
1. Detect the undocumented 0xdeadbeef return value and interpret it as
a failure.
2. Avoid allocating that high.
(2) is really the cleaner solution here. 768MB is plenty of room so use
that as the max alloc_top instead of 1GB.
